resistance of a new or good battery, and decide the limits for judging
battery wear.
As a battery wears out, its internal resistance increases to
approximately 1.5 to 2 times (reference value) that of a new or
good battery, and voltage values decreases to 90% of the default
value. Use these values as guidelines when determining the battery
wear judgment values.
